Gt235E Won't Start

I just serviced my circa 2004 GT235E tractor to start the season. I had to replace the battery. It wouldn't ttake a charge and the positive terminal was corroded beyond anything I have seen before. Started and ran fine with new battery. The wife mowed the lawn with the bagger as usual for the first mowing. I then completed oil change, converted deck to mulching mower, lubed, fluids, cleaned, etc. The mower ran fine without problems. The mower wouldn't start then nest time. With key in run position, the lights are sporadic. The battery light is not always on. I heard a loud click when trying to start several times. The mower then started several times.

Now back to same thing. Nothing when I turn the key. The green LED light is lit on the circuit board connected to the starter switch. I suspect this is a starter switch or ignition board problem? Any help with troubleshooting? I was unable to locate a wiring diagram to help.

Welcome to GTtalk ! not familiar with your Gt. Any pics , and does it have a solenoid? I'm pretty sure somebody more helpful is on the way. Hang in there and rest that hammer down on the workbench Hopefully it'll be an easy fix. Goodluck

Welcome to GTTalk. Sounds like you have a bad connection somewhere, possibly in the ignition switch itself. I don't have any service info for that model no. Perhaps someone else can help with an diagram of the electrical system. Since the lights are sporadic as well as the starting it could be the ignition switch or perhaps a bad chassis (ground) connection.

No diagram here either, I would start with testing the battery (just because it's new doesn't mean anything) next remove and clean battery cables and make sure they are tight and the ground is good on frame(remove & clean), next would be tightness of any wire you can see, hopefully that may solve the problem.
